British Security Minister Ben Wallace said Thursday that Russian President Vladimir Putin had "ultimate" responsibility for a nerve agent attack on a former Russian double agent in England in March.

LONDON (Reuters) - A British woman died on Sunday after she was poisoned by the same nerve agent that struck a former Russian spy in March and triggered a crisis in relations between Western capitals and Moscow.

The nerve agent Novichok has poisoned two new victims in England, The Telegraph reports. The two collapsed after visiting Salisbury, the same town where former Russian double-agent Sergei Skripal and his daughter Yulia were attacked with the chemical weapon back in March.
